When to make Chlorine?

[Theusla]

There is a difference in manually chlorinating a pool and using a SWG. When you add chlorine manually you add it all at once. With a SWG a little is being added through out the pump run time.
I run my pump for 8 hours in N FL ....5 hours from 10 am to 3 pm and then three more hours from 6 to 9 pm.

What is the advantage of doing a split run time?

I run my filter at night and SWG mostly 24/7, but I'd run it at night if I didnt run it all the time. Mostly because I get a cheaper electricity rate at night.

Sunlight destroys chlorine, it doesnt matter where it comes from. Not sure if that affects how you should opperate a SWG for optimal cell life.

Tredge, I can't go agaist Ben (not that it's illegal, just that he knows sooo much more than I). However, with an auto chlorinator, I suggest turning it on manually when people are using the pool and letting it run for 1/2 hour after they finnish swimming - this puts cl in the water as the 'bad' stuff is going in (having everyone rinse off before entering the pool will lessen the cl demand). I usually recommend a 'split' run time to allow the chlorinator to run while the pool is in use and a cycle at night to do as Ben says and let the chlorine really do it's job when there is no interference from bathers or sun.
